Begonia plant named &#39;silver splendor&#39;

ABSTRACT

A new and distinct form of  Begonia  plant characterized by deeply cut maple-shaped leaves, heavily silver-spotted foliage, and vigor.

BOTANICAL DENOMINATION

Begonia hybrid

VARIETY DESIGNATION

‘Silver Splendor’

PARENTAGE

Begonia hemsleyana×Begonia taliensis

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia, of the family Begoniaceae, and given the cultivar name, ‘Silver Splendor’. This plant originated from planned cross between Begonia hemsleyana, as the seed parent, and Begonia taliensis, as the pollen parent. All the seedlings in the cross had slightly different versions of deeply divided maple shaped leaves. This selection was made for its deeply cut maple-shaped leaves, heavily silver-spotted foliage, and vigor. This combination of traits is unique in Zone 7 hardy Begonia.

Compared to the seed parent Begonia hemsleyana, the new cultivar has leaves that are heavily silver-spotted and blotched between the veins rather than plain green to lightly spotted and leaves that are simple and deeply palmately divided rather than palmately lobed. Compared to the pollen parent, Begonia taliensis, the new cultivar is taller with leaves that are deeply palmately divided rather than shallowly palmately lobed.

The new variety has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by micropropagation as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Begonia cultivar based on observations of a one-year-old specimen grown in the ground in a shade house in September in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart.
